Description

  The present invention relates to, for example, a paper sheet processing apparatus that picks up and conveys a plurality of stacked newspapers one by one.

  In general, an apparatus for separating and separating a plurality of stacked paper sheets one by one is a mechanism for shifting a plurality of stacked paper sheets in a scissors-like manner, and rubbing against the tip of a paper sheet that has been shifted in a scissors-like manner. It has a mechanism for pulling out by applying force. As this type of device, for example, a paper board is arranged on one side of the stacking direction of a plurality of paper sheets shifted in a scissors shape, and a paper feed roller is provided on the opposite side of the paper board with the paper sheets in between. Arranged devices are known.

JP 2008-110824 A

  In the above-described conventional apparatus, if there is a variation in the conveying posture of the paper sheet, or the paper sheet is bent or bent, the leading edge of the paper sheet shifted in a scissors shape is placed between the separating plate and the paper feed roller. It may not be inserted properly. In this case, for example, there is a possibility that the leading edge of the paper sheet hits the supply roller and bends to cause a paper sheet jam.

  Further, in the above-described conventional apparatus, when the type or thickness of the paper sheet changes, it becomes difficult to normally feed the leading edge of the paper sheet shifted in a scissors manner between the scooping plate and the paper feed roller. Therefore, in this case, it is necessary to adjust the gap between the separating plate and the paper feed roller.

  Furthermore, even if the gap between the paper board and the paper feed roller is adjusted according to the type and thickness of the paper sheet, the second and subsequent paper sheets that overlap the first paper sheet are accompanied. There was a case where double feeds were generated.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a paper sheet processing apparatus capable of reliably separating and taking out accumulated paper sheets one by one.

FIG. 2 is a schematic view showing the collating mechanism 10.
The collating mechanism 10 has a substantially rectangular parallelepiped casing 1 that is long in the Z direction. On the front side (the left side in the figure) and the back side (the right side in the figure) along the Y direction of the housing 1, a plurality of paper feed trays 2 arranged in the Z direction are provided. Each paper feed tray 2 is attached to be inclined downward toward the inside of the housing 1. In each sheet feeding tray 2, several types of folding inserts t are stacked and loaded. It is also possible to insert the same type of inserts t through a plurality of paper feed trays 2. Note that the lowermost paper feed tray 2a on the front side of the housing 1 is assigned as a paper feed tray for loading origami s (FIG. 3). The origami s may be a kind of a folding paper t.

  In the housing 1, a transport path 3 extending in the Z direction through the center of the housing 1 is provided. The conveyance path 3 is provided along the XZ plane between a plurality of paper feed trays 2 on the front side and a plurality of paper feed trays 2 on the back side. In other words, the folding leaflets t taken out from each paper feed tray 2 at a predetermined timing are sent to the transport path 3 and overlapped with each other. Then, a plurality of folded sheets t in an overlapped state are conveyed downward via the conveyance path 3. The conveyance path 3 is provided with a plurality of conveyance roller pairs 4 for nipping and conveying the plurality of folded sheets t in an overlapped state.

  A first paper feed roller 5 and a second paper feed roller 6 are provided at the lower end side of each paper feed tray 2 in the inclined direction, that is, at the end closer to the center near the transport path 3, respectively. The first paper feed roller 5 rotates in contact with the folding edge t at the uppermost end of the plurality of folding edges t put on the paper feeding tray 2. The second paper feed roller 6 provided on the downstream side of the first paper feed roller 5 in the direction of taking out the folded sheet t presses the tip of the second and subsequent folded sheets t against the separating plate 7 to prevent the two sheets from being removed. . A feed roller pair 8 is provided downstream of the second paper feed roller 6 along the paper feed direction of the folding paper t, and feeds the folding paper t into the transport path 3.

  A folding roller pair 9 is disposed at the lower end of the conveyance path 3. The folding roller pair 9 is provided in such a posture that its nip is positioned on an extension line of the transport path 3. That is, a plurality of folding margins t conveyed downward through the conveyance path 3 are fed into the nip of the folding roller pair 9.

  In order to feed the folded paper s introduced through the paper feed tray 2a to the upper side of the pair of folding rollers 9 on the downstream side (right side in FIG. 2) of the paper feed tray 2a for feeding the folded paper s. The feed roller pair 8a is provided. At the leading end of the origami s in the paper feeding direction, a stop unit 11 is provided that stops the leading end of the origami s at a predetermined position. The stop unit 11 stops the origami s at a position where the center position of the origami s in the sheet feeding direction faces the nip of the pair of folding rollers 9. A folding knife 12 for pushing the central portion of the origami s toward the nip of the folding roller pair 9 is disposed obliquely above the folding roller pair 9.

  In other words, the folding paper t introduced through each paper feed tray 2 is overlapped in the transport path 3 and sent to the nip of the folding roller pair 9. At this time, the center of the origami s fed in advance is folded in advance by the folding knife 12. Then, a plurality of folding sheets t conveyed through the conveyance path 3 in an overlapped state are pushed into the center of the origami s, and are sandwiched between the origami s by the rotation of the folding roller pair 9. A bundle of folded leaflets that have been folded into two by passing through the pair of folding rollers 9, that is, a collated bundle T (FIG. 3) in which a plurality of folded leaflets t are sandwiched between origami s, are delivered to the conveyor belt 13. Then, the paper is discharged from a discharge port 15 provided on the front side of the housing 1 through the discharge roller pair 14.

  FIG. 3 is an external perspective view showing an example of the collating bundle T discharged from the discharge port 15 of the collating mechanism 10. The collated bundle T is discharged in the Y direction with the leading end T-1 side in the discharge direction (Y direction) covered with the origami s. In the present embodiment, one end s-1 along the discharge direction of the origami s (the right end portion as viewed from the discharge direction) is aligned with the end t-1 of the plurality of folded sheets t. The paper feed position along the X direction of the origami s can be adjusted so that T is discharged.

  As shown in FIG. 1, the newspaper supply mechanism 20 includes a loading unit 21 that loads a plurality of newspapers P in an upright position. As shown in FIG. 4 (a), the newspaper P is folded from the state in which a plurality of A1 size newspapers are stacked, as indicated by the arrow in the center, and further folded into an A2 size as shown in FIG. 4 (b). In a state where a plurality of newspaper sheets folded in half are folded in the direction indicated by an arrow at the center broken line (in a state folded in four) (news folded in approximately A3 size) (FIG. 4c) in a stacked state. It is input to the input unit 21.

  The posture of the newspaper P inserted into the insertion unit 21 is an orientation in which the direction indicated by the arrow Y ′ in FIG. 4C faces downward (an orientation obtained by reversing the top and bottom), and an orientation with the fold line P-1 down. is there. That is, the plurality of newspapers P are stacked in the Y direction with the lower portion P2 contacting the upstream belt 31 (described later) facing rearward when the newspaper P is fed into the newspaper handling mechanism 30 (described later) and is fed to the input unit 21. It is thrown.

  The newspaper supply mechanism 20 takes out the newspaper P in the order from the rearmost newspaper P out of the plurality of newspapers P that are input in a stacked manner via the input unit 21. At this time, the two take-out belts 22 and 22 that are in contact with the lower part P2 of the rearmost newspaper P are run downward, and the lower side of the newspaper P starts with the fold P-1 (see FIG. 4C). (In the direction indicated by arrow Y ′). There are cases where two or three copies of the newspaper P are taken out together. The newspaper P taken out from the input unit 21 is sent to the newspaper handling mechanism 30 arranged below the input unit 21. For this reason, the newspaper P sent to the newspaper whispering mechanism 30 is in a posture opposite to that shown in FIG. 4C, and the above-described arrow Y ′ direction is aligned in the Y direction.

  FIG. 5 is a schematic view showing the configuration of the newspaper whispering mechanism 30, and FIG. 6 is a plan view of the newspaper whispering mechanism 30 of FIG. The newspaper handling mechanism 30 once stacks the newspapers P sent from the newspaper supply mechanism 20, separates them one by one from the newspaper P at the lower end, and conveys the separated newspapers P to the newspaper opening mechanism 40. The direction in which the newspaper P is conveyed by the newspaper handling mechanism 30 is the X direction, which is orthogonal to the direction in which the newspaper P is supplied by the newspaper supply mechanism 20 (Y direction).

  The newspaper rolling mechanism 30 is stacked on the upstream belt 31 for stacking newspapers supplied from the newspaper supply mechanism 20, the downstream belt 32 (conveying means) adjacent to the downstream side in the traveling direction (X direction) of the upstream belt 31, and the upstream belt 31. A newspaper roller P (sliding means) that shifts the newspaper P in a scissor manner in cooperation with the upstream belt 31, and the newspaper P at the lowermost end that is scissored is sandwiched between the downstream belt 32 and separated from other newspapers P. And a conveying roller 35 that conveys the newspaper P separated one by one by the separating roller 34 to the newspaper opening mechanism 40. The upstream belt 31 gives a conveying force to the newspaper P that is in contact with the upper surface 31a. The newspaper whispering mechanism 30 will be described in detail later.

  The newspaper opening mechanism 40 opens the upper portion P1 (FIG. 4c) of the newspaper P separated one by one by the newspaper whispering mechanism 30 to a suction member (not shown) and opens upward. The position at which the upper portion P1 of the newspaper P is adsorbed is a portion on the downstream side in the X direction near the end opposite to the fold P-1 and close to the fold P-2. The suction member is provided with a suction hole for applying a negative pressure to the upper portion P1 of the newspaper P, and the suction side end of a blower (not shown) is connected to the suction hole. And by operating a blower, the upper part P1 of the newspaper P is adsorbed by the adsorbing member.

  The newspaper opening mechanism 40 has a drive mechanism (not shown) that moves the suction member upward. The newspaper opening mechanism 40 has a guide plate (not shown) on which the upper portion P1 of the newspaper P that is attracted by the adsorption member and opened upward is placed. Further, the newspaper opening mechanism 40 may have a blower (not shown) that sends wind between the newspapers P opened by the adsorption member.

  In the newspaper P, the fold line P-1 is disposed in the front in the Y direction, the fold line P-2 is disposed on the downstream side in the X direction, and the lower part P2 (the part visible on the upper side in FIG. 4c) is the downstream belt. It is moved in the X direction in contact with the upper surface 32d of 32. For this reason, when the upper part P1 of the newspaper P is adsorbed by the adsorbing member, the upper part P1 is separated from the lower part P2 and lifted, and a gap is formed between the lower part P2 and the upper part P1. The guide plate is inserted into this gap with the conveyance of the newspaper P by the downstream belt 32.

  On the other hand, the collation bundle T discharged from the discharge port 15 of the collation mechanism 10 is sent toward the insertion position above the downstream belt 32. The guide plate of the newspaper opening mechanism 40 is disposed above the insertion position and supports the upper portion P1 of the newspaper P from below. For this reason, the collation bundle T discharged from the discharge port 15 of the collation mechanism 10 is inserted into the gap between the lower part P2 and the upper part P1 of the newspaper P.

  As described above, the set K (not shown) with the collated bundle T sandwiched between the newspapers P is accumulated on the stacker 51 (FIG. 1) of the collated bundle aligning mechanism 50. The collating and bundling mechanism 50 includes an X-direction striking plate (not shown) that taps one end in the X direction of the set of sheets K accumulated on the stacker 51, and a Y-direction striking plate (not shown) that taps one end in the Y direction of the collected sets K. Have. These two hitting plates are connected to a motor (not shown) via a link mechanism (not shown), the X direction hitting plate vibrates in the X direction, and the Y direction hitting plate vibrates in the Y direction.

  The elevating mechanism 60 has a receiving tray 61 disposed adjacent to the downstream side in the X direction of the collating and aligning mechanism 50. A mechanism for moving the receiving tray 61 up and down is disposed in the housing 1 of the collating mechanism 10. That is, a motor (not shown) that moves the receiving tray 61 up and down along the Z direction is provided in the housing 1.

  A plurality of sets of paper sheets K that are stacked in the collating and aligning mechanism 50 and whose edges are aligned are transferred onto the receiving tray 61 of the lifting mechanism 60 by a carry-out mechanism (not shown). Then, the plurality of sheets K is lifted by the lifting mechanism 60 and moved to a height at which an operator can easily take it out.

Hereinafter, the detailed structure of the above-described newspaper whispering mechanism 30 will be described with reference to FIGS.
The newspaper supply mechanism 20 has a supply roller 24 that supplies a plurality of newspapers P, which are input in a stacked manner through the input unit 21, to the newspaper handling mechanism 30. The supply roller 24 has two pairs of rollers spaced apart in the X direction. Each roller pair has two roller portions that rotate with the newspaper P interposed therebetween. An upstream belt 31 of the newspaper handling mechanism 30 is disposed obliquely in front of the supply roller 24. The supply roller 24 is disposed in such a positional relationship that the newspaper P can be supplied at an angle at which the fold P-1 of the newspaper P hits the upper surface 31a of the upstream belt 31. The newspapers P supplied via the supply roller 24 are stacked on the upper surface 31 a of the upstream belt 31.

  The upstream belt 31 is stretched endlessly around a pair of belt rollers 31b and 31c extending in the Y direction and spaced apart in the X direction. The upstream belt 31 is a rubber belt having a relatively large surface friction coefficient, for example. The upstream belt 31 is provided such that its upper surface 31a is parallel to the horizontal plane. The upstream belt 31 travels so that its upper surface 31a moves in the X direction. The upper surface 31a mentioned here refers to the outer surface of the upstream belt 31 in which the surface of the upstream belt 31 faces upward in the course of traveling. That is, all the surfaces of the upstream belt 31 can be the upper surface 31a.

  In front of the upstream belt 31 in the Y direction, an abutting wall 71 (FIG. 6) that is erected in parallel with the XZ plane is disposed. In FIG. 5, the butting wall 71 is not shown. The abutting wall 71 abuts and stops the leading end (that is, the fold line P-1) of the newspaper P sent to the newspaper scooping mechanism 30 via the supply roller 24. Specifically, the newspaper P sent from the newspaper supply mechanism 20 abuts the fold P-1 at the abutting wall 71 after abutting the fold P-1 at the tip against the upper surface 31a of the upstream belt 31 and stopping. Is done. At this time, if the newspaper P is already accumulated on the upper surface 31a of the upstream belt 31, the fold P-1 of the newly fed newspaper P collides with the upper surface of the accumulated uppermost newspaper P. Then, the newspaper P newly fed while sliding on the upper surface of the uppermost newspaper P is overlapped.

Two alignment plates 72 and 73 are arranged on the opposite side of the abutting wall 71 in the Y direction with the upstream belt 31 interposed therebetween. Aligning plate 72 and 73 are spaced apart from each other and the monitor X-direction is parallel to the XZ plane, is connected to a motor 212 (FIG. 7) via a link mechanism (not shown). The aligning plates 72 and 73 vibrate in the Y direction and hit the end opposite to the fold line P-1 of the newspaper P placed on the upper surface 31a of the upstream belt 31. Thereby, the newspaper P is aligned between the butting wall 71 and the two alignment plates 72 and 73. The interval in the Y direction between the butting wall 71 and the two alignment plates 72 and 73 is substantially the same as the width of the newspaper P in the Y direction.

  Above the upstream belt 31, a support plate 74 that supports a part of the newspaper P before being supplied via the supply roller 24 and placed on the upper surface 31a of the upstream belt 31 is disposed. In the present embodiment, the support plate 74 is disposed at a position spaced above the upstream belt 31 at a position near the end of the upstream belt 31 on the downstream side in the X direction. More specifically, the rear side in the Y direction (alignment plate 72, of the X direction tip side of the newspaper P (the outline is shown by a broken line in FIG. 6) sent from the newspaper supply mechanism 20 onto the upper surface 31 a of the upstream belt 31. The support plate 74 is arranged at a position to support the part that is offset to the (73 side). For this reason, the support plate 74 can partially support the tip in the X direction of the newspaper P fed onto the upper surface 31a of the upstream belt 31 from below.

  The support plate 74 is attached to be rotatable about a rotation shaft 74a extending in the Y direction. The support plate 74 can be disposed at a support position (a position indicated by a broken line in FIG. 5) that partially supports the newspaper P when the surface on the downstream side in the X direction is pushed by the solenoid 213. When the newspaper P is sent toward the upper surface 31a of the upstream belt 31 through the supply roller 24 in a state where the solenoid 213 is turned off and the support plate 74 is disposed at the retracted position along the Z direction indicated by the solid line in FIG. The newspaper P does not interfere with the support plate 74 retracted from the supply path of the newspaper P. In this case, the newspaper P is supplied directly toward the upper surface 31 a of the upstream belt 31 without contacting the support plate 74.

  The newspaper whispering mechanism 30 has a downstream belt 32 adjacent to the downstream side in the traveling direction (X direction) of the upstream belt 31. The downstream belt 32 includes two endless downstream belts 32a and 32b that are spaced apart from each other in the Y direction. The Y-direction rear edge of the downstream belt 32 a disposed rearward in the Y direction is disposed flush with the Y-direction rear edge of the upstream belt 31. Further, the front edge in the Y direction of the downstream belt 32b disposed in front of the Y direction is flush with the front edge of the upstream belt 31 in the Y direction. The downstream belts 32a and 32b are rubber belts having a relatively high surface friction coefficient.

  The end portions of the downstream belts 32a and 32b on the downstream side in the X direction are not shown. The downstream belts 32a and 32b are stretched endlessly around a pair of belt rollers 32c (downstream belt rollers not shown) that extend in the Y direction and are spaced apart in the X direction. ing. The width in the Y direction of the downstream belt 32a at the rear in the Y direction is wider than the width of the downstream belt 32b at the front in the Y direction.

  The downstream belts 32a and 32b are provided in such a posture that their upper surfaces 32d are parallel to the horizontal plane. The downstream belts 32a and 32b travel at the same speed so as to move on the upper surface 32d in the X direction. The upper surfaces 32 d of the downstream belts 32 a and 32 b are disposed in substantially the same plane as the upper surface 31 a of the upstream belt 31. The upper surface 32d here refers to the outer surface of the downstream belts 32a and 32b in which the surfaces of the downstream belts 32a and 32b face upward in the course of traveling. That is, all the surfaces of the downstream belts 32a and 32b can be the upper surface 32d. The upper surfaces 32d of the downstream belts 32a and 32b function as conveyance surfaces.

  Two shifting rollers 33a and 33b (hereinafter sometimes referred to collectively as shifting rollers 33) are disposed above the belt roller 31c on the downstream side in the X direction around which the upstream belt 31 is wound. The shift roller 33 is disposed at a position where a part of the shift roller 33 also overlaps the end of the downstream belt 32 on the upstream side in the X direction. The shift roller 33 is disposed on the downstream side in the X direction from the support plate 74 described above. For this reason, the newspaper P sent to the newspaper handling mechanism 30 via the supply roller 24 does not interfere with the shifting roller 33.

  The shift roller 33 is disposed in contact with the upstream belt 31. That is, the upstream belt 31 is sandwiched between the belt roller 31 c and the shift roller 33. The shift rollers 33a and 33b are rotatably provided around a rotation shaft 33c extending in the Y direction. The two shift rollers 33a and 33b are provided coaxially apart from each other in the Y direction. The shift roller 33 is biased toward the belt roller 31c by its own weight, and is biased toward the belt roller 31c by a spring (not shown).

  The newspaper P placed on the upper surface 31a of the upstream belt 31 is conveyed in the X direction by being given a conveying force by the frictional force generated between the upper belt 31 and the upper surface 31a as the upstream belt 31 travels. When the newspaper P is conveyed by the upstream belt 31, the shift roller 33 is pushed upward according to the thickness of the newspaper P. At this time, when a predetermined amount of frictional force is applied from the newspaper P to the shift roller 33, the shift roller 33 can be rotated around the newspaper P. In other words, the shifting roller 33 is given a torque that stops rotation when a predetermined amount of frictional force is not applied from the newspaper P, and is taken out by the newspaper P that contacts the upper surface 31a of the upstream belt 31. It functions to shift the newspaper P in a scissors-like manner and separate it.

A separating roller 34 is disposed between the two downstream belts 32a and 32b. The winding roller 34 is disposed above the downstream belts 32a and 32b so as to face the ends of the downstream belts 32a and 32b on the upstream side in the X direction. The rolling roller 34 is vertically moved between a lower end position where the lower end intersects the conveying surface including the upper surfaces 32d of the two downstream belts 32a and 32b and an upper end position where the lower end is positioned slightly above the conveying surface. It is provided to be movable. In the state where the newspaper P is not conveyed, the web roller 34 is urged toward the lower end position by its own weight, and is disposed in a nested manner between the two downstream belts 32a and 32b.

  The rolling roller 34 is a roller made of rubber at least on the surface, and the X-direction leading end of the lowermost newspaper P, which has been shifted in a scissors-like manner and fed from the upstream belt 31 to the downstream belts 32a and 32b, is downstream belts 32a and 32b. Between them. In this state, when the downstream belts 32a and 32b travel in the X direction, the lowermost newspaper P pressed against the upper surface 32d of the downstream belt 32 by the winding roller 34 is pulled out in the X direction. At this time, the tip end of the newspaper P in the X direction is pressed and curved by the two downstream belts 32a and 32b and the nest roller 34 arranged in a nested manner, so that the newspaper P is strained.

  A conveying roller 35 is provided between the two downstream belts 32a and 32b. The conveying roller 35 further conveys the newspaper P drawn and separated in the X direction by the separating roller 34 in the X direction and sends it to the newspaper opening mechanism 40. . The conveying roller 35 is arranged to be separated from the downstream side of the separating roller 34 in the X direction. The conveyance roller 35 includes two roller portions 35a and 35b arranged so as to sandwich a conveyance surface including the upper surfaces 32d of the two downstream belts 32a and 32b. That is, the front end in the X direction of the newspaper P that is placed and transported on the upper surface 32d of the downstream belts 32a and 32b is fed into the nip between the two roller portions 35a and 35b of the transport roller 35 and is held and restrained. It is further conveyed in the X direction by the rotation of the conveying roller 35.

  A sliding sheet 36 (low friction member) is attached to the upstream side in the X direction of the rolling roller 34. The sliding sheet 36 is a flexible plate-like member made of plastic, for example, and is formed of a material having a relatively small friction with the newspaper P. The sliding sheet 36 has an upper end in the Z direction fixed to a support portion (not shown) that supports the rolling roller 34, and a lower end extending toward the lower end of the rolling roller 34. For this reason, when the rolling roller 34 moves up and down, the sliding sheet 36 follows the rolling roller 34. The lower end of the sliding sheet 36 is disposed at the lower end of the sliding sheet 36 so that the front end in the X direction of the newspaper P, which is shifted between the upper surface 31a of the upstream belt 31 and the shift roller 33, can be brought into contact with the outer peripheral surface of the roller 34. Is extended to a position spaced a few millimeters upward from the conveying surface. Thereby, even if the thickness of the newspaper P fluctuates and the separating roller 34 moves up and down, the outer peripheral surface of the separating roller 34 can be exposed with a certain width. The sliding sheet 36 has a width slightly larger than the width of the rolling roller 34 in the Y direction, and is disposed in contact with the outer peripheral surface of the rolling roller 34. The sliding sheet 36 is provided so as to be inclined so that the lower end is located on the downstream side in the X direction from the upper end.

FIG. 7 is a block diagram of a control system that controls the operation of the newspaper handling mechanism 30.
The control unit 200 of the newspaper handling mechanism 30 has a sensor 201 (detection means) for detecting whether or not the newspaper P is supplied on the upper surface 31a of the upstream belt 31, and the nip of the transport roller 35 at the front end of the newspaper P. A sensor 202 for detecting passing is connected. Sensors 201 and 202 are transmissive sensors each having a light emitting unit that emits a light beam that intersects a conveyance surface on which the newspaper P is conveyed, and a light receiving unit that receives a light beam emitted from the light emitting unit. Alternatively, the sensors 201 and 202 may be reflective sensors that receive the reflected light of the light emitted from the light emitting unit with a light receiving unit disposed on the same side of the transport surface.

  The control unit 200 includes a motor 211 for driving the supply roller 24, a motor 212 for operating the alignment plates 72 and 73, a solenoid 213 for operating the support plate 74, a motor 214 for driving the upstream belt 31, a downstream belt 32a, A motor 215 for driving 32b and a motor 216 for rotating the transport roller 35 are connected.

  Hereinafter, the processing operation by the control unit 200 of the above-described newspaper whispering mechanism 30 will be described with reference to FIGS. 8 and 9. FIG. 8 is a flowchart for explaining the operation of the support plate 74. FIG. 9 is a timing chart for explaining the operation timing of the upstream belt 31 and the downstream belt 32.

  First, the control unit 200 determines whether or not the newspaper P is placed on the upper surface 31a of the upstream belt 31 via the sensor 201 (FIG. 8, step S1). At this time, when the light beam emitted from the light emitting unit of the sensor 201 is received by the light receiving unit, the control unit 200 determines that there is no newspaper P on the upper surface 31a of the upstream belt 31, and does not receive the light beam by the light receiving unit. In this case, it is determined that the newspaper P is placed on the upper surface 31a.

  When it is determined that there is no newspaper via the sensor 201 (step S1; NO), the control unit 200 energizes the solenoid 213 to rotate the support plate 74 to a support position indicated by a broken line in FIG. 5 (step S2). In this state, when the first newspaper P is supplied toward the upstream belt 31 via the supply roller 24 (step S3; YES), the downstream end of the newspaper P in the X direction is supported by the support plate 74. The newspaper P is placed on the upper surface 31 a of the upstream belt 31 while being supported.

  After rotating the support plate 74 to the support position in step S2, the control unit 200 rotates the support plate 74 to the retracted position at a predetermined timing before the next newspaper P is fed toward the upstream belt 31. (Step S4). The predetermined timing here is preferably a timing at which the second newspaper P does not interfere with the support plate 74.

  As described above, when the first newspaper P is fed into the upstream belt 31, the newspaper P is bent by its own weight by supporting the downstream end portion of the newspaper P in the X direction by the support plate 74. be able to. As a result, the newspaper P can be strained, and the upper surface 31a and the newspaper P can be moved during the movement of the newspaper P until the newspaper P is placed on the upper surface 31a of the upstream belt 31. The contact area between them can be reduced. In this way, by reducing the contact area between the upper surface 31a and the newspaper P, the moving newspaper P is caught by friction with the upper surface 31a of the upstream belt 31, and the accumulated posture of the newspaper P is increased. Disturbances can be prevented.

  On the other hand, if the support plate 74 is not operated when the first newspaper P is fed toward the upstream belt 31, that is, if the support plate 74 is left in the retracted position, the newspaper P It moves while contacting the upper surface 31a of the upstream belt 31 in a relatively large area. In this case, the newspaper P is caught on the upper surface 31a, and the posture is easily disturbed. If the posture of the newspaper P placed on the upper surface 31a of the upstream belt 31 is disturbed, the processing accuracy in the newspaper opening mechanism 40 on the downstream side is lowered, and the possibility of jamming is increased. Therefore, in the present embodiment, the newspaper P is partially supported by the support plate 74 only when the first newspaper P is supplied to the upstream belt 31.

  When the second copy of the newspaper P is sent to the upstream belt 31, the first copy of the newspaper P is placed on the upper surface 31a of the upstream belt 31 (step S1; YES), so that the second copy of the newspaper P is sent. P accumulates while sliding on the upper surface of the first newspaper P. In this case, it is not necessary to arrange the support plate 74 at the support position, and the support plate 74 is arranged at the retracted position (step S5).

  For this reason, the second copy of the newspaper P does not come into contact with the upper surface 31a of the upstream belt 31, and there is no fear that the posture will be disturbed by being caught by the upper surface 31a. In other words, in order to stabilize the stacking posture of the second and subsequent newspapers P, it is necessary that the preceding newspaper P always exists on the upper surface 31a of the upstream belt 31. For this reason, in the present embodiment, the upstream belt 31 and the downstream belt 32 are caused to travel at a timing at which the newspaper P does not disappear on the upper surface 31a of the upstream belt 31.

  That is, the control unit 200 starts the running of the upstream belt 31 and the downstream belt 32 in a state where a plurality of newspapers P are accumulated on the upper surface 31a of the upstream belt 31 (FIG. 9, timing T1). As a result, a plurality of newspapers P accumulated on the upper surface 31 a of the upstream belt 31 are sent in the X direction toward the downstream belt 32.

  When the accumulated plural newspapers P are conveyed in the X direction by the upstream belt 31, the shift roller 33 is pushed up by the thickness of the newspaper P. At this time, a conveying force is applied from the upstream belt 31 to the lowermost newspaper P that is in contact with the upper surface 31 a of the upstream belt 31 among the plurality of stacked newspapers P. On the other hand, the second and subsequent newspapers P that are not in contact with the upper surface 31a of the upstream belt 31 are conveyed by the upstream belt 31 by being blocked by the torque acting in a direction to stop the rotation of the shift roller 33. The lowermost newspaper P is separated. Since the shift roller 33 can be moved upward by the pressing force applied from the newspaper P, the plurality of newspapers P stacked on the upper surface 31 a of the upstream belt 31 has the newspaper P on the lower end side close to the upstream belt 31. It is shifted in a scissors shape so as to be conveyed in advance.

  After starting the traveling of the upstream belt 31 and the downstream belt 32 at the timing T1, the control unit 200 monitors the output of the sensor 202 provided downstream of the transport roller 35, and in the X direction of the separated and transported newspaper P. When the leading end passes through the nip of the conveying roller 35 (timing T2), the traveling of the upstream belt 31 and the downstream belt 32 is temporarily stopped. In this state, the transport of the second and subsequent newspapers P is stopped, while the first newspaper P is pulled out in the X direction by the transport rollers 35.

  The control unit 200 stops the travel of the upstream belt 31 and the downstream belt 32 at the timing T2, and then restarts the travel of the downstream belt 32 at the timing T3. Then, the control unit 200 stops the travel of the downstream belt 32 again when the rear end in the transport direction of the first newspaper P passes through the nip of the transport roller 35 (timing T4). As a result, the first newspaper P can be reliably sent downstream, and the second and subsequent newspapers P can be reliably separated.

  As described above, the operation of T1 to T4 is repeated until there is no newspaper P sent to the upstream belt 31 via the supply roller 24, thereby reliably separating and transporting a plurality of stacked newspapers P without jamming. can do.

Hereinafter, the functions of the rolling roller 34 and the sliding sheet 36 will be described.
As described above, the newspaper P shifted in a scissor shape by the action of the shift roller 33 is fed between the separation roller 34 and the downstream belts 32a and 32b. At this time, the tip in the X direction of the lowermost newspaper P contacts the sliding sheet 36 and is guided toward the gap between the upper surface 32 d of the downstream belts 32 a and 32 b and the leading end of the sliding sheet 36. In other words, the front end of the newspaper P is pressed against the surface of the sliding sheet 36 inclined downward from the upstream side toward the downstream side, and the leading end slides downward along the sliding sheet 36, and the rolling roller 34 and the downstream belts 32a and 32b. It is sent in between. Thereby, the front-end | tip of the said newspaper P can be reliably sent between the rolling roller 34 and the downstream belts 32a and 32b.

  On the other hand, if the slip sheet 36 is not provided, the front end of the newspaper P may come into contact with the outer peripheral surface of the scooping roller 34 at a position spaced upward from the upper surface 32d of the downstream belt 32, which may cause a jam. That is, the position where the front end of the newspaper P contacts the outer peripheral surface of the rolling roller 34 may vary, and the newspaper P may be folded or bent. For example, when the conveyance posture of the newspaper P is varied or the newspaper P is bent or bent, the leading edge of the newspaper P may not be inserted between the downstream belts 32a and 32b and the scooping roller 34 in some cases.

  Therefore, in the present embodiment, the sliding sheet 36 is provided in order to reliably feed the front end of the newspaper P between the rolling roller 34 and the downstream belts 32a and 32b. The sliding sheet 36 is set to an appropriate value for the gap between the upper surface 32d of the downstream belt 32 so that only the leading edge of the newspaper P at the lowermost end is fed between the roller 34 and the downstream belts 32a and 32b. .

  On the other hand, the web roller 34 can be disposed at the lower end position nested with the downstream belts 32a and 32b by its own weight, so when the leading edge of the newspaper P is inserted between the web roller 34 and the downstream belts 32a and 32b, The front end of the newspaper P is curved and given a strain to the newspaper P. Thus, the newspaper P can be easily pulled out by the downstream belt 32 and can be reliably separated from other newspapers P.

  Further, even when the thickness of the newspaper P is changed by urging the rolling roller 34 toward the lower end position by its own weight as in the present embodiment, the space between the rolling roller 34 and the downstream belts 32a and 32b. The tip of the newspaper P can be inserted securely. In this case, it is not necessary to adjust the gap between the winding roller 34 and the downstream belts 32a and 32b according to the thickness of the newspaper P, and convenience can be improved.

  Furthermore, according to the present embodiment, the separation roller 34 moves up and down according to the thickness of the newspaper P without adjusting the gap between the separation roller 34 and the downstream belts 32a and 32b. There is no problem of double feeding in which a plurality of newspapers P are sent in an overlap between 32a and 32b.

In addition, this invention is not limited to embodiment mentioned above, It can change arbitrarily, without exceeding the range of invention. In the above-described embodiment, the case where the present invention is applied to an apparatus that separates and extracts a plurality of accumulated newspapers P one by one has been described. However, for example, an accumulated magazine, book, or booklet such as a passbook is 1 The present invention can also be applied to an apparatus for separating and taking out parts one by one.
